Hi Pete,

The PSU should read 5.1v on it's output.

Your issue will be that this will probably drop momentarily when the system initialises... You won't be able to see that on a multimeter!

The best bet is to order a replacement ECM60UT31 and swap it over.

Any problems, give me a shout.

Cheers,

Steve
